Abstract

The utility model discloses a double-beam electric hoist, which relates to the field of electric hoists. The double-beam electric hoist comprises a lifting motor, operating motors, a coiling device, a lifting transmission box, a frame and a hook assembly. The lifting motor is a double-speed motor with a disc brake and drives the coiling device through the transmission box. The operating motors are installed on the frame, and an operating motor is installed on each of two sides of the frame. Each operating motor provides the operating power to the frame on the side independently. The two operating motors operate synchronously. The hook assembly is connected to the coiling device. The double-beam electric hoist provided by the utility model is reasonable in structure and ensures the safe production by using the double-speed motor with the disc brake. Two operating motors are used to provide the operating power to the frame so that the frame operates more stably, therefore, the use efficiency of production is improved.

Description

A kind of double beams electric hoist

Technical field:

The utility model relates to a kind of electric block field, is specifically related to a kind of double beams electric hoist.

Background technology:

Electric block is called for short electric hoist, it is a kind of small-sized crane gear, generally be divided into two kinds of steel-wire rope type electric block and Electric Chain Blocks, the ordinary steel wire rope electric hoist is single-beam suspension formula electric block, this electric block is arranged on a crossbeam, lifting bear the weight less, it is twin-spar construction that the only a few electric block is also arranged, but under normal circumstances, the electric block great majority that are arranged on twin beams provide operation power for single motor for it, easily produce operation and steadily easily do not cause potential safety hazard

And much the motor of equipment is that common motor does not have safety arrestment mechanism, causing easily overwork to increase potential safety hazard.

The utility model content:

Technical problem to be solved in the utility model is to overcome the defective of prior art, and a kind of double beams electric hoist is provided.

Technical problem to be solved in the utility model realizes by the following technical solutions: a kind of double beams electric hoist, comprise lifting motor, the operation motor, roll device, change speed gear box hoists, vehicle frame and cargo hook gear, described lifting motor is the double-speed motor with the disc type drg, lifting motor drives roll device by change speed gear box, described operation motor is installed on the vehicle frame, the vehicle frame both sides are separately installed with an operation motor, each operation motor independently provides operation power for the vehicle frame of place one side, the running of two motors keeps the phase mutually synchronization, and described cargo hook gear is connected on the roll device.

The utility model project organization rationally adopts double-speed motor with the disc type drg for the safety of producing provides guarantee, adopts two operation motors for vehicle frame provides operation power can be so that the vehicle frame operation be more steady, thereby improved the service efficiency of production.

Description of drawings:

Fig. 1 is plan structure scheme drawing of the present utility model;

Fig. 2 is construction profile scheme drawing of the present utility model;

Wherein: the 1-lifting motor; 2-moves motor; The 3-roll device; The 4-change speed gear box that hoists; The 5-vehicle frame; The 6-cargo hook gear.

The specific embodiment:

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

As illustrated in fig. 1 and 2, a kind of double beams electric hoist, comprise lifting motor 1, operation motor 2, roll device 3, change speed gear box 4 hoists, vehicle frame 5 and cargo hook gear 6, described lifting motor 1 is the double-speed motor with the disc type drg, this motor is when temperature reaches upper limit (UL), thermally dependent resistor or sensor will cut off the motor power supply, for production operation provides safety control, lifting motor 2 drives roll device 3 by change speed gear box 4, so just guaranteed the stability of equipment when hoisting, described operation motor 2 is installed on the vehicle frame 5, vehicle frame 5 both sides are separately installed with an operation motor, each operation motor independently provides operation power for the vehicle frame of place one side, the running of two motors keeps the phase mutually synchronization, like this with regard to so that the running velocity on vehicle frame both sides is identical, thereby has guaranteed vehicle frame traveling comfort and property at the uniform velocity, described cargo hook gear 5 is connected on the roll device 3, carries out lifting to weight by the rotation of roll device 3.

More than show and described groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification sheets just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
